The Tipping Point

Intro: This is a total work of my imagination. Any resemblance to anyone on this planet is just your imagination. Yes, I have sisters. We never banged. You can't think I'd write something I could get sued over. Half siblings, Shelby (29) and Jason (27) have moved back in with their mother, Katherine (49). Jason and Donna have fallen in love, but what about Shelby?

*****

"I'm nervous about this, Jase. I don't want to piss her off."

"Well I'm not ready to lose her. I just fell in love with her. This is bullshit, not taking our calls and not returning texts." Jason said with anger in his voice and desperation in his heart.

In the two weeks since Anna's wedding, Donna has been withdrawn. She saw Jason and Shelby a few times but seemed distant and scared. Now the siblings have staked out a table beside the pool of the hotel that Donna helps manage. They have vowed to sit there until she comes to talk. They both love her and that's the problem.

Finally, Donna Smith emerged from the lobby of The Roadside Pioneer. She slowly and purposefully walked to the pool area. "I guess you two aren't going to leave until I come out here."

"Hey, baby. We just want to talk to you. We love you." Shelby pleaded. "Please sit a minute."

"Look, the fact that both of you love me and I love you is the problem. It's fucking with my head." Donna said fighting back tears that came anyway. "I can't do this here. I'll try to come over tonight or tomorrow night and we'll talk about this."

"Bullshit!" Jason surprised the girls with his forceful tone. Yet he was not loud. "Please don't make me pace the floor at home hoping. This is everything to me. I love you and I'll do whatever it takes to make this work. I've missed you like a lost limb all this week."

Tears streamed down Donna's face. Jason looked at Shelby and she was crying too. "You two calm down and get your shit together. Donna, we'll come to your apartment at seven tonight. We will make this work because love matters." Well, that got Jason's tears falling.

Donna heard his words and felt his heart. She looked up at him with the sparkle back in her eyes despite the tears. "You mean that, don't you?" Shelby squeezed her hand.

...

Jason and Shelby left the hotel when Donna was able to go back in.

"I know what is fucking with her head." Shelby said. "So, she comes over. Who does she sleep with? She won't sleep with me because of you. She won't sleep with you because of me."

"She has an apartment. She has her own place." Jason said.

"Look, you big dummy, it's the same, really. I go off with her, she thinks of you. If she goes off with you, she worries what it will do to me." Shelby lectured.

"She knows it's OK with me that you are lovers. And she knows you've been pushing us together for two months." Jason said.

"Who, me?" Shelby smiled. "I didn't think she would hang on to me like this. Love is very strong in this one, ass-hopper."

Jason rolled his eyes and sighed at Shelby trying to be funny while his heart hurt so much.

"We've just got to tell her." Shelby said flatly.

"Oh, fuck no. If she finds out we had sex, she'll freak the hell out and we'll never see her again."

"Maybe not. Then we could have it all. We could both openly love her. Imagine holding her in your arms while I pet her. It would be beautiful." Shelby the sales person.

"And what happens when I start petting you. She's going to freak. I tell you, she's too old-fashioned for that shit."

...

The siblings walked up the stairs to Donna's apartment. "This is a nice building. I don't know why she says she hates this place." Jason said.

"Bad memories and a few bad neighbors. She moved in here after her divorce. Some of the men around here were relentless. Thus, the birth of 'Bitch Donna'" Shelby told him.

"Two condemned for the hangman." Jason mused.

"Don't be so dramatic. I'm betting my love on this, too."

Donna answered the door in loose house clothes. "Hey, you two." She hugged each and then all in a group hug. "This would be easy if I didn't love you both. Come in. Sit."

Shelby started. "Look, I'll give you up, if you and Jason will be happy."

"I knew you were going to say that." Donna snapped. "It's not as easy as that."

"I know you want the family and the white picket fence." Shelby said.

"I know, I want kids. You think I prefer men, but I have really come to enjoy women. When Anna turned me on to it, it was just a way to find some comfort. I found out it's something special. I love you both. Jason are you strong enough to have a bisexual woman, even if she has a girlfriend?" Donna asked him.

"Yes, but only if it's all honest. I couldn't have someone cheat. Also, I'd do anything to have a woman like you in my life."

"See he's cool with you being with me." Shelby said, thinking it was settled.

"Well I'm sorry Shelly. It's still fucked up. I'd think of him with you and think of you when I'm with him. I did when we went to the wedding. I had the best day of my life, but you were in the back of my mind. And we can't be a triple because you two are siblings. It's fucked up." Donna teared up and dropped her head to her hands.

"We can be. It doesn't have to be fucked as bad as you think. It's just fucked up in a different way."

"Don't Shell. You can't. We'll work this out. There's a way. There must be. Please don't." Jason pleaded.

"What's he talking about? Don't what?" Donna asked

"Look, I love you. I know we just got started, but it's real. I've never known a woman like you. Just always know that I love you." Jason began to weep heavily and closed himself in the bathroom.

"Shell, what's wrong with him?" Donna asked concerned.

"He thinks he's about to lose you." Shelby said calmly but with tears running down her small face.

"He won't lose me if we can figure this out. He's the best guy I've ever met." Donna trembled.

"Baby, you have to listen and understand that all this is my fault. I'm too selfish. I wanted it all and no one can have it all. I love you and I love Jase and I wanted you two to be together. I just never thought it would come to this. You two are so perfect for each other. I'm so sorry, Baby. Please don't hate Jason."

"Shelby, what the fuck are you going on about? Calm down. Take a breath." Donna held her hands.

"I'm so sorry. It's my fault. I teased him and went naked in front of him. I showed my body and made him kiss me." Shelby could hardly speak for sobbing. "It was during a time when you and I weren't seeing each other. I kept teasing him and one day we got stoned and fucked. Jason and I had sex."

...

Donna found Jason reclining in her bathtub. He had rolled up a towel for a pillow and had a wet cloth over his eyes. "Get your stupid, hillbilly ass out of my tub and get in here. Big dumbass!" Donna stormed out of the bathroom.

Jason climbed out of the tub and slowly walked out the door like a man stepping into the gas chamber. He was ambushed at the door. Donna threw her arms around him and hugged and kissed him.

"Oh, tell him what you told me before drops dead." Shelby said from the sofa. Her eyes were red and swollen but she was smiling.

Donna was silent until she came back from the kitchen. She set the tequila bottle and a shot glass on the coffee table and sat in her favorite chair. She poured a modest ration and threw it back in one swallow. "OK for now you can't talk unless you take a shot first. That was mine. I'll start." Donna smiled at the incestuous duo. "I always assumed that you two had at least experimented with sex. God, look at the two of you. Jase you are gorgeous and Shell, you've got the hottest little ass I've ever seen"

Jason took a shot of tequila and sat back.

"Well, sir you have the floor." Shelby said.

"Oh, I just needed a drink." Jason said seriously. But the girls laughed loudly.

"Shelby if you were my sister, we'd be lovers if I had to force you. Jason if you were my brother, we'd probably have some twelve toed kids by now." Donna tried to console the two.

Shelby took a shot. "It's my fault. It just got to where I had to feel that big dick in me."

Donna took a sip. "That's how you knew how big his dick is. She told me you had a seven-inch dick."

"Seven and a half on a good day." Jason pleaded. Both girls pointed at the tequila. He took a big gulp from the bottle. "I wondered why she just walked in my room and asked how big it is."

"No, I ask him. Then he showed me." Shelby confessed. Jason handed her a shot and she killed it. "She asked but I wanted to know. I know you guys all measure then add two inches."

Jason took a small shot and spoke. "Baby it was just one week back in June. The tension just built until we snapped and did it... for a week." Jason felt the alcohol sinking in. "We acted out some fantasies we had been having. Then we stopped. We stopped because you came back to Shelby and I wanted to impress you with the dance lessons."

Donna drank a shot that Shelby had poured. "You did impress me, baby. No one has ever done anything for me like that. Well, lovers, I've had my fantasies too. I thought of slipping down the hall, away from Shelby and sitting on your cock. Shelby, I've thought of three ways for us but you too being siblings was the killer."

Shelby took a drink from the bottle. "I'm a slut and I wanted you two to be sluts too." She slurred.

Jason sat dumbfounded as Donna hit the bottle. "OK you two, I'm swearing you to secrecy of the highest order." Donna said.

"Oh, as if we weren't already..." Shelby spoke but Donna pointed at the tequila.

"Wait, Shell. I'm spilling something I've sworn to take to my grave and I don't feel like dying today." Donna crossed her heart. "I fucked my brother."

Shelby took a shot and Jason followed. "You are shitting me!" Shelby called out. "Dish the details my fellow slut."

"Don't call my girl a slut." Jason slurred. The girls laughed.

"OK, truce on the tequila. I haven't eaten." Donna said shaking her head. "I'm getting drunk as hell. Shell, order a pizza. OK, kids. It was back when we heard that Marko was killed in the Army. Everyone came around acting like I was a grieving widow. Shit! I was a bitter ex-wife. I wanted to celebrate. I've never been so happy someone died."

"Not even Bin Laden?" Jason asked, drunk.

Donna chuckled. "No, no one."

Shelby's eyes swam around, "Ben who?"

"So, I got David to take me to Panama City Beach." Donna blushed. "I wanted to party. I wanted to get drunk. I wanted to get laid. The weather was bad. There was nobody there but us and some smelly fishermen. David and I smoked a joint on the beach one night. I asked him to make love to me. He resisted but he wanted it too. We fucked for two days. He'd die if he knew I told. He was already married and had his first kid."

"How was it?" Shelby asked.

"Shelby!" Jason scolded. "I can't believe you."

"He was sweet and loving like Jason, Shell. See, I'm worse than you two perverts. Of course, Dave and I aren't in love like you two hillbillies. You guys kiss way too much."

Jason and Shelby blushed red and laughed.

...

A jug of soda came with the pizza. Conversation normalized, somewhat. "Damn, I feel better now that I ate. That liquor on an empty stomach was wicked." Shelby announced. She slipped gently into Donna's lap and kissed her passionately. "Now I can kiss you with dumbass in the room." She smiled.

"Don't call my boyfriend a dumbass." Donna said with a smile.

Shelby hopped up laughing. "Oh, shit. That's how it's going to be. Huh?"

Jason leaned and kissed Donna. "Yes dwarf. That's how it's going to be." He grinned and kissed Donna again.

Shelby raised her mock protest. "I'm not a dwarf. I'm three inches too tall to legally be a dwarf. And, we prefer the term 'Little People'".

"Two inches at most, little person" Jason had a kiss for Shelby. They all relaxed around the living room. Jason holding Donna and Shelby admiring the couple. "We haven't been together since we got back from the wedding, baby. Could we move this party to the bedroom?"

"Can we not jump right into hardcore orgy stuff. I've never had a threesome." Donna said.

"Me neither." Jason added and they both looked at Shelby.

"Oh, fuck y'all. So, I've done some stuff, OK?" Shelby walked over to the couple and took their hands. "I think this might be beautiful."

...

Donna, in tee shirt and panties, took the middle of the bed. Shelby took the right in just panties and Jason on the left in his boxers. They all worked on getting comfortable. Shelby sent a text to Katherine explaining that they were hopelessly drunk and crashing at Donna's place.

"Guys, I'm serious about taking this slowly." Donna pleaded.

"I'm with you, babe. This is a very delicate way to start. At least we all love each other to start with. We aren't working through that now too." Jason said.

"You two are the honeymooners. I should let you guys have some privacy but I'm so glad everything didn't go to shit tonight, I want to be here with you tonight. Is it OK?" Shelby asked.

"Yes, dear. I want you here. You've known all along that this could fall apart." Donna said and kissed Shelby.

"Later, I want to know just how much of this plan you were party to. That was weeks ago that Shelby asked how big my dick was." Jason said to Donna. Both girls giggled. "What have I gotten myself into?"

Shelby moved down to Donna's hips and pulled her shirt up enough to kiss around on her belly. Jason gently pulled Donna's face to his and they began to kiss. They kissed easy at first the added more and more passion. Shelby slipped Donna's panties off and ran her fingers through her close-trimmed pubes. Jason helped Donna out of her shirt. He cupped her breast in his hand and kissed her again. Shelby slowly slipped in between Donna's legs and kissed around her pussy. Jason began to suck and kiss her breasts flicking here nipple ring with his tongue. Shelby knew the rhythms of Donna's body and began to probe the folds of her pussy with her tongue. Donna reached for Jason's cock and pulled it out of the fly of his boxers. She stroked it as Shelby licked harder on her pussy. Shelby watched Jason's cock being stroked beside her face. She reached over and pulled his boxers down disturbing Donna's action for a second. Shelby saw that Jason's pleasure had increased to the point that he was hunching and fucking Donna's hand. Shelby got off Donna's pussy and moved beside her. She nodded to Jason. He moved over between Donna's legs and slowly slid his hard cock into her wet pussy. Donna looked up into his eyes and smiled. He settled into a nice rhythm and Shelby cuddled up to Donna and began licking and sucking her perfect tits. The sight of Shelby sucking Donna's nipples mesmerized Jason. He slipped his hand into Shelby's panties and pushed a finger into her pussy. In full sensory overload. Donna launched into one of her tamer orgasms. Jason felt himself beginning to cum. At the last second, he pulled his cock out and shot cum all over Donna's delicate belly. The girls cooed with approval. Jason moved beside Donna and kissed her lovingly. Shelby mopped up the semen with tissues and settled beside Donna.

"Wow you two are amazing. That was so nice. I can't believe how natural that felt." Donna said.

"You two are as beautiful together as I imagined." Shelby said proudly. "OK, let's see hands of every one that has fantasized about that." Shelby asked. She and Donna stuck hands in the air and looked at Jason. He slowly raised his hand. They all laughed.

"Honey, Shelby did me so good, but she got left out. She didn't cum at all. Look she's still got her damn panties on. This will not do." Donna said and moved onto her knees and between Shelby's legs. She pulled Shelby's panties off as Jason began to kiss and fondle his sister. Donna wasted no time beginning to lick and suck on Shelby's pussy.

Jason raised up on elbow and watched as Donna expertly ate Shelby's little pussy. He had often thought of these two licking. His cock began to throb back to life. The familiar scent of Shelby's pussy filled the room. He sniffed the finger he had had in her.

Donna lapped at Shelby's cunt and reached over to squeezed Jason's hard cock. When she realized that he was rock hard again she knew what had to happen. She moved over and pulled Jason over onto Shelby. She stared with amazement as Jason got into position and pushed his cock into Shelby. Donna almost orgasmed again at the sight of Jason's cock sliding in and out of her lover and his sister. She rose beside him and kissed him passionately. Shelby reached for Donna's hand. She guided Donna to straddle her chest and place her pussy on her face. Donna kissed as the lovers they were as Jason fucked and Donna face sat Shelby. Intensity built as the three lovers began cumming. Donna first spasmed and pushed cream into Shelby's mouth. Shelby had been holding back but feeling Donna cum triggered her to start cumming and Jason joined in and came inside Shelby.

"Holy shit!" Shelby said. "Good thing you two didn't want to do any hardcore orgy shit." They all laughed and got comfortable again with Donna in the middle.

Donna reached down to Shelby's pussy and played with the cum that was draining out. "Lucky girl. I wish I could let Jase cum in me."

"You can, baby." Shelby grinned. "Nothing would make Katherine happier.

"Oh, hey, that reminds me. Do you know who else thinks that you two have had sex? Katherine!"

...

In the early morning light, Jason and Donna had moved the coffee table. Jason sat on a towel in the center of the sofa, nude. Donna was on her knees between his legs wearing only a long silky robe spread wide open. She was gently beginning to kiss and play with his cock. "I can still smell Shelby's pussy on you and on my fingers." She whispered. "It's an amazing odor. I'm quite addicted to it." Donna took the cock in her mouth and sucked it to full hard.

"Yeah, she smells great. It gets to me too." Jason said softly.

Donna sucked and stroked Jason's cock for several minutes before she climbed up into his lap. She stuck the fingers that she had in Shelby earlier under Jason's nose. "Oh, she smells so hot." She whispered in his ear. "That scent makes your cock hard, doesn't it? It's makes my pussy wet." Donna rose up and sat down, taking Jason's hard dick all the way into her wet pussy. She kept whispering to him. "You feel so good in me, baby. I've wanted you inside me for so long. Push, Jase. That's it. Oh, I'm so full." Donna moaned. "Those muscles you have. The first time I saw you without a shirt, I wanted to suck your cock right there, in front of Shelby. Now I can do it. I can suck you and fuck you with Shell watching like last night. It was so wonderful." Donna moaned and bounced on Jason's cock like crazy. "Oh, Jason. I love you and her so much. Watching your cock go in her made me cum. Cum like now." Donna quivered and began hunching and pumping until she collapsed on Jason's chest. Jason kept pumping from underneath and the pulled her hips up and backed out of her. Jason's thick cum shot out in a pool on his belly. They held each other motionless for some time. "I do love you, Jase."

"I love you, Baby. I'm so happy." Jason answered.

...

Shelby found Donna in her kitchen. She hugged her tightly. What smells so good?"

"I've got some instant blueberry muffins in the oven and coffee made." Donna answered.

"Aren't you the perfect hostess? Baby last night was more that I could ever hope for. Thank you for being who you are." Shelby beamed smiling.

"Don't start me crying this morning. I'm so happy I could burst. Jason and I made love again this morning, while you were sleeping. Too bad you both have to work the lunch today." Donna said. "I'm going to make room for you two to leave some things here."
